Tomcat 8中的JSP編譯錯誤

Question

以前我使用的是tomcat 7.0.30，最近使用的是tomcat 8.0.21

之后，每當我嘗試訪問我的應用程序時，都會出現如下所示的JSP編譯錯誤，

返回類型與JspSourceDependent.getDependants（）不兼容

還有下面的錯誤

對於類型JspFactory，未定義方法getJspApplicationContext（ServletContext）

我也在使用GWT 2.7.0和SmartGWT PRO 4.1

您能為此建議解決方法嗎？ 我瀏覽了建議的鏈接，但沒有幫助。 將支柱更新至2.3.20

使用-verbose：class VM參數在下面發布完整的stacktrace，

Answer 1

如果包含gwt-dev.jar文件，則將其刪除。

我最近有這個問題。 當存在一個包含JspFactory定義的有沖突的jar時，通常會發生這種情況，如下所述：

對於類型JspFactory，未定義方法getJspApplicationContext（ServletContext）

對於GWT，請檢查是否包含gwt-dev.jar文件。 它還包含JSPFactory的定義。 這就是我遇到問題的原因。 去掉它。 您可能在運行時不需要它，也不需要包含jar。
